HP printer (all-in-one) and ink

This printer/scanner/copying machine works but got slower a bit - and sometimes paper gets jammed. I don't know if it's a hardware or a firmware problem. It works though! It's making me so angry at times so I'm getting rid of it! If you're tech-savvy enough to tame it, please take this with you. I'll give you one black inkjet as well. I think the ones in the printer dried out.
